Yeah, it depends on the kind of story. A suspense often has anger or violence, when there's a villain out to get the boys or something. But if it's more anger/violence in a relationship or something, that'd be more drama. I use drama as a catch-all when I'm not sure what else to call it - if it's not a comedy, it must be a drama LOL. Angst I see as a subcategory of drama, when the story focuses a lot on a character's emotional pain and sadness. I'd say all angsty stories are dramas, but not all dramas are angst.
